1. Find the Fourier Cosine and Sine transform of
f(x) = 1; if 0 x 1
0; if x > 1
Use the results to show that
cosx 2
a) R01 1 x dx = 2
b) R01 sinx22x dx = 2

Kayla made observations about the sellin price of a new brand of coffee that sold in the three different sized bags she recorded those observations in the following table 6 is $2.10 8 is $2.80 and 16 is to $5.60 use the relationship to predict the cost of a 20oz bag of coffee.
